Darryl Steffen (dobu gabu maru)

Darryl Steffen, known by his alias dobu gabu maru, is an American level designer, and host of The DWmegawad Club since its inception. He was named as the Mapper of the Year at the 2017 Cacowards, in addition to receiving a Cacoward for Saturnine Chapel and a Machaward for his monsterless puzzle map The Given.

Steffen is known for his highly idiosyncratic style, with common tropes being difficult, cruel combat setups, extravagant, richly detailed environments, ambitious concept levels, and meticulous worldbuilding. He also has a fascination with puzzle maps; besides The Given, his other levels in a similar style include Moonlight and his Exuviae levels such as.

Steffen is also noted for his community project management efforts. He co-led NOVA: The Birth, and was the project lead for its sequel. In 2017, he playtested and did major mapping work for TNT: Revilution. One of the levels he retouched, his collaboration Transduction with Stupidbunny, Kyka, and Megamur, placed 90th in Doomworld's Top 100 Most Memorable Maps.
